Lustily

"So 'bro' did you enjoy watching your little step-sister play with herself? Did you like watching her fuck herself with a big dildo?"

With you unable to say anything coherent she continued

"I bet you were going to go to go to your room and jerk off, dreaming that you were fucking her and playing with her cock?! You pervert! Do you know what is the really pathetic thing about that?"

You notice the smirk on her face and glint in her eye when you shake your head.

"That you were watching her in the hallway when you could be in my room playing with me!"

As your brain struggles to process this information Amber leans in and kisses you deeply. After a second you return the kiss and opening your mouth to allow her invading tongue to duel with yours. You use your arm to bring her closer to you. As a result her huge breasts mash up against your chest.

Eventually you break off the kiss. You look at Amber; her tits rising and falling spectaculary as she is gasping for breath. You turn your gaze lower to her skimpy shorts and notice that there is a VERY big bulge potruding from them.

"You got a penis too?!" You ask. A mixture of shock and excitement evident in your voice.

Amber nods in confirmation with a wicked grin on her face."Let's go back to my room" Amber says once she catches her breath "then you will get a real show" she adds with a wink.
